I trained a 750K-parameter world-model agent on my M5 Pro to play video games! Presenting NanoDreamer: a tiny Dreamer-inspired agent that learns game dynamics and trains an actor–critic in latent imagination. Write-up: benjamin-bai.com/projects/na…

so encouraging to see tech twitter go off with truths that make us sing :D
This Friday, I’ll be giving a talk on the historical case for the resurrection of Christ. Several years ago, I began looking into the historical evidence as an atheist to prove that Christianity was nothing but a therapeutic superstition. What I found completely changed my life. Over the course of a year, I spent nearly every waking moment reading whatever I could find on the subject. My entire life was suddenly reorganized around answering this one question: did Jesus Christ actually rise from the dead? There was a time when I thought this question was too ridiculous to even consider. But looking back, it was by far the most important question I've ever asked. If you're interested in learning more, check out the link to the event page below. All are welcome to join regardless of religious background or lack thereof.

nice
I've been looking into public benchmarks and am astounded by the poor quality vs. how much we rely on them as an industry. @xeophon pointed me to this excellent site epoch.ai/benchmarks/ which is an independent third party which scrutinizes benchmarks and "looks at the data" 💪 For example, here are some popular benchmarks we all rely on. Before trusting a benchmark its worth running them and inspecting examples the grader failed carefully, to get a sense of the quality. I'm continuing to look more into this, and will write something up eventually once I've collected more data, but I think this is an important subject.

What still limits a sub-2 marathon? And could a second fuel move it? I wrote a technical analysis on running economy, durability and exogenous lactate. It has more questions than answers, on purpose. 🧵

i get asked VERY frequently to chat about data / RL envs / new companies coming into the space. all of the questions tend to be exactly the same so i want to summarize my thoughts: Q: "Should I start a data company?" A: probably not, unless you have some sort of alpha or have seen what frontier RL envs are like. basically, if you're not deep within an industry, seen data via a lab or working at another data company, or very well connected with lab researchers, you probably should not. though, if its your passion, now is the best time and it'll get increasingly worse. data is also much harder now than it was 6 months ago, and quality standards are ever-increasing. Q: "Is there a product in the space?" A: i think there are repeatable systems that can be created. i.e. QA systems, faster task generation, infrastructure around rollouts/VMs/GPU utilization/prod. system emulation etc. i think data is inherently bespoke, luckily LLMs allow you to harness bespoke intellect infinitely. i don't think it's a SaaS style product where it serves everyone immediately, but more of a quant-desk type system with alpha on how to do specific tasks embedded within an engineer-system like manner. each eng will have a desk that serves them specifically that unlocks 10x, 100x, 1000x capabilities. Q: "Is {insert set} data valuable" A: depends on what you do with it. raw data dumps are cool but it's a lot more about what you can turn it into. Q: "How does {insert data company} differ from {insert competitor}?" OR "Should I join {insert data company}?" A: if you're in the "big, legacy" data companies with contractors, it doesn't really differ that much. if i had to pick, i'd probably join mercor or surge from the big contractor companies, by virtue of early employees/founders being extremely smart. however, i'd much rather join a small, research-heavy data company. they are by far the companies with the highest slope. Q: "Won't labs just in-house this anyway?" A: (1) data is an additive game that isn't zero-sum. just because labs are increasing synthetic data creation internally does not mean they won't buy more data. especially given it is an arms race to the top of intellect, if you can just make valuable data that moves the needle, it doesn't really matter if they can replicate it, it's not worth their researcher time if you solve a problem. the caveat being you have to actually add something yourself, and not just be a parrot who takes requests. saving researcher time is the name of the game. (2) i think this logic applies to everything, if you adopt this mentality, you probably should not work at any applied AI company, since they'll come after or absorb most products in the space.

great reflections! excited where you will take these learnings to, onto the next!!!

Heard today from an AI data entrepreneur: "Contractors are gaming the system that data companies have developed. They're just spinning up synthetic pipelines themselves. When I was a student, I did contracting for ML tasks with a data company. I set up a system where I was just using Gemini 2.5 pro to complete all the tasks, and they never noticed." The provenance and quality of data has never been more important.

Biology lags code by about a year. But there are strong + unintuitive technical parallels.

This has been insanely fun to work on for the past couple weeks! This rewrite tested the limits of all our products: thousands of subagents via Prime Agent, billions of tokens via Prime Inference, and hundreds of sandboxes via Prime Sandboxes! It's incredibly rewarding to see our full stack come together, and Prime Agent is now faster than ever :)

as a runner, moving to SF meant improvising a run (as I often did in London/Santa Monica) could send me up a small mountain ... so I built: flattensf.com

agree with the spirit of this! hopefully this is not too reductively computational...
We need a Christian METR. For theology to shape the trajectory of artificial intelligence, it cannot remain confined to philosophical generalities: it must translate those concerns and commitments into the computable argot of evaluations, harnesses, and environments.

Replying to @SaladCoInc
@SaladCoInc will be presenting LakeQuest tomorrow at COLM - come find us! Paper #1073 poster session: Poster 1 (Tuesday Morning 11am) Poster room: Franciscan Poster number: F-1-135
1/QA systems do well on benchmarks built from clean, curated text. But that's not where real knowledge lives. In companies and labs, it's spread across tables, documents, and metadata that barely link together. LakeQuest tests QA in that setting.

I am at COLM until Friday - please email/find me if you’d like to chat about grad school or faculty jobs at Waterloo! The R2L lab will be looking for 1-2 PhD students, please see r2llab.com
